Ethnic cleansing in Croatia is a method which was used by Croats several times to change the balance in national composition of Croatia in twentieth century. It went hand in hand with genocide against the Serbs and foibe massacres of the Italians in WWII, but the method was used again in '91-'95 Croatian secession war. Some Germans, who lived in Slavonia, were also expelled, but their number was not so large as Germans were a small minority there. While Germans were nazis up to '45, Italians fought on the side of Allies since '43, like they did in the WWI.
